  • When anyone talks about Holocaust these days, it’s reasonable to assume they talk about the one vs the Jews by Nazi Germany. It has gained a special meaning unlike the more generic word genocide, which is perfectly fine for other use cases. The Holocaust was a genocide, not every genocide is a Holocaust.

    If you want to go semantic/etymological, calling the current Palestine genocide a Holocaust still makes no sense, as the old Greek holocaust literally means “full incineration”, burning sth so nothing is left. Which makes sense in association with Nazi crematoriums, and its historic use for large fire catastrophes such as whole cities burning down.

    It also made - semantically - sense for Neonazis in Germany who called the fire-bombings of German cities by the Allied in WW2 holocausts as well. This also tries to form a link and somehow equate two entirely different things. Both atrocities by modern standards, sure, but at vastly different levels.

    (Mis-)appropriating terms to undermine and diffuse their meaning is a simple and effective populist tactic, which is why it’s popular with extremists.

    Call a genocide a genocide, call the Holocaust the Holocaust.

    The world is full of nuance, not just radicals and extremes.

    Nice of you to provide such a prime example of lack of education. Equating current events in Palestine and Israel with the actual Holocaust is absurd. I’m pretty certain Israel has not industrialized genocide at the level Nazi Germany did, and I’d be very surprised if Israel was exclusively killing Jews. Because those are two fundamental elements of the term Holocaust.

    Stop diffusing the meaning of words with very specific meaning like Holocaust.

    Also, great job of providing nothing to the actual topic at hand and derailing it with whataboutisms.




  • Why do you consider telegram private? It’s a pretty bad option for that. They are only using true end-to-end encryption when using the explicit “secret chat” feature, which is limited to one-on-one still, afaik.

    “Normal”/default encryption gets resolved on telegram servers, so your clear text messages are sitting there for them to do whatever they want. Given that telegram is based in UAE and has knownRussian management influence,I’d be extra hesitant.

    It also is for-profit and closed-source for the servers ( only clients are open source), so nobody knows what the servers really do.

    If you care about privacy, go use Signal or any Matrix-based messenger such as Element. Especially because they lack zero of the comfort and usability that Telegram offer, but are much more secure.


  • Inherited a Hilti Hammer drill from my dad that was used for basically everything in construction and demolition he ever did since before I was born - around 4 decades ago. It was and is the tool he and now me always go to when cheaper drills can’t deal with the problem. Be it hammering through super massive concrete walls or enduring hours-long destruction sessions, it just does the job.

    Nowadays it looks like a utter piece of junk that got tumble dried with rocks, but it’s as reliable as on day one.


  • Regarding the profit incentive: providing free school lunches or medical/ hygiene supplies does not hurt profits. As the meals/supplies will still have to be sourced from the market, it probably will now be a few big contacts with big suppliers that will cover entire school districts.

    The costs of these contracts will be a public burden unless they implemented a specific focus tax to pay for it, so it will come out of various broad tax pools. This means everyone pays a little bit so every kid has something to eat. Even if you don’t have any kids or if your kid gets homemade lunch packs. This is where the “social” aspect comes in.

    Other countries, many of them European, actually go a step in the other direction: if you do not have kids, you actually pay a premium on your income tax. And that is generally accepted, because for society to live on, obviously kids are necessary. And if you don’t support society by raising kids, you at least help cover some of the associated costs. These premiums are explicitly used to fund kindergartens, schools etc…

    An often valid capitalist criticism of public large contracts on infrastructure such as this is that the public offices tend to be notoriously bad negotiators, accepting worse deals than private companies would. This is because there’s little to no incentive for them to reach good terms. It also makes the process more vulnerable to corruption and politicking on a grander scale. These are not guaranteed to happen, good governance can definitely avoid this. But public governance simply isn’t that great to begin with in many areas.




  • Antlion itself an official wireless modmic, but it’s a staggering 150 bucks, was cheaper a could years ago… On the upside, it’s pretty much a lifetime purchase and really good quality. But it’s definitely overpriced.

    If your budget is lower, you can look at lavalier mics or wire mics. Those are the kind that TV/ video guys usually wear. Lavaliers are simply tacked to the top of your shirt, while the wire mics are super thin wires that you wear under your actual headset. Both are light, have good audio quality and nur importantly are available at much wider and fairer price ranges, as they are less of a nice. Lav mics can be as cheap as ten bucks.


  • I have invested lots of effort and research and sadly money over the years into this specific question. And nowadays my recommendation would be: keep it simple.

    That means: get a headset that is well reviewed and uses a wireless connection. Do not use Bluetooth. Bluetooth has good quality now, but no matter what perfect settings you use, you will have a noticeable delay, which is especially noticable during hectic gaming voice comms. Some headsets with a dedicated wireless receiver ( usually a small USB dongle) offer BT as an extra option, which can be great if you want to use it for listening to music or doing occasional calls while moving outside while linked to your phone.

    Second tip: don’t get a combined all-in-one gaming headset. They can be good, but are always overpriced für what they offer. Marketing ftw. Instead get a good headset and get a simple separate mic. Modmic or any derivative works.

    Overall, you’ll get tremendously better quality for significantly less price. The sheer amount of options for good “generic” headphones is immense. Added bonus: because the two are separate, you can swap one out when it breaks. Especially the addon microphones have a tendency to last decades, unlike the headsets themselves, which suffer more immediate wear and tear.



  • A lost bat might get trapped in a dark room. While they wouldn’t be bothered too much by the dark ( like everyone else, they need at least a bit of light to see using their eyes ), they could use echo sounding to figure out the room fairly well. But they still would be unable to open the door or window to escape, so still trapped or “lost”.

    My attempt at an interpretation. 😅



  • The efficacy of vaccines usually declines over time after administration. The immune system starts to “forget” how to fight a pathogen it doesn’t encounter. It doesn’t completely forget, but it puts the treatment data way back in the archives. So when it encounters the real deal, it can take quite a while to boot up production of antibodies. It also varies by the type of disease.

    This is fine for some slow diseases ( which is why sometimes a single vaccination can suffice ), but can be risky if the disease progresses faster than the immune system can ramp up the defenses.

    Administering the vaccine as soon as possible after suspected exposure to deadly or highly contagious diseases simply helps the immune system to get the necessary blueprints to get in the fight quicker.

    Administering the vaccine before any exposure at regular, long intervals is done to decrease the baseline risk. Sometimes you don’t know you have been infected. Many diseases are not only transmitted by dramatic, obvious vectors. In those cases, it’s definitely better to have some old defense than none at all.


  • Taste is actually a valid and very important identifier used for classifying minerals during geology field work when there is no access to advanced diagnostic tools. For health reasons, it’s obviously not the primary method, but it usually follows the “scrape test”. Scraping the mineral over a known hard surface tells a whole lot about hardness, texture, color, granularity…



  • I’m keeping your soda bottle analogy:

    In this case, a very strong eruption ejects kids of super hot gas and rock upwards, like when you open a shaken bottle. After some time, pressure will decrease, and gravity will start dragging things down again.

    Unlike a regular soda bottle, heat is significant. Hot gas rises in the atmosphere against gravity. During this rise, it loses energy ( so it cools down). When it reaches a high enough temperature where the lifting momentum is overcome by gravity, it starts falling again.

    As the top starts to fall while there still is more material below in the column, the column gets compressed. As the center of the column is the hottest part, it still pushes material upwards. So the colder material falling from the top is pushed outwards, widening the column a bit. It also encounters the cold air outside and starts cooling even more itself, falling ever faster in the outside “ring” of the column. It still is only “cool” compared to the rising inner column, still thousands of degrees. Also, all the light glasses will have moved further up the atmosphere and either fall slower or not at all. This is where the long term effects such as your mentioned ash fall/ rain comes from. So most of the rapidly falling material that then form pyroclastic flows are actually fairly heavy liquids/solids and heavier-than-air gasses. They only seem so light and fast inside a pyroclastic flow because if their immense temperature and contained energy.

    However, sooner or later the falling material encounters the ground, a solid obstacle. As the inner column is densely filled with super hot, probably still rising fresh material, the only possible way is outwards. And with continuous pressure from above from all the falling material, the material needs to move out of the way very rapidly. This is not dissimilar from how water behaves that flows from a bottle or faucet and hits solid ground. But a pyroclastic flow is a bit more viscous, and still very hot. While moving outwards, it quickly has to push away the cool, resting atmosphere. The only way for the air is to step aside upwards. Now, as the cold air likes to stay close to the ground and was compressed, it forms a seemingly paradoxical barrier layer of cold, dense air above the pyroclastic flow, pressing down on it, even squeezing it further outwards. This together with it’s own viscosity means there’s surprisingly little turbulence between the two layers, with the hot flow continuing to rush along below the cold barrier layer instead of mixing and rising through it upwards. If this interests you, look up inversion layers: they are a normal phenomenon in regular weather as well, especially winter time, and can sometimes even last many days.

    Consider that ash columns reach many km in altitude, filled with many tons of material. It doesn’t all fall slowly at the same time. It’s literally rock falling from high atmosphere to the ground, carried by heavier-than-air gasses that also want to sit below the atmosphere.
